Review on Flex Lite 31165 Variable Control by Jarrett Young

I bought this controller because it was one of the few on the market with useful features that allow you to control multiple fans from one controller without a separate relay. Reliability has not yet been determined, but the kit contains almost everything you need. The only thing I had to buy was a different size battery clip than the one that came in the kit. I also bought extra connectors, heat shrink tubing, and a flexible cord cover from Home Depot for a few dollars. The fans work amazingly on this controller. I hooked it up to two 16" Zirgo Hi-Flow fans in parallel on a '98 Ford Expedition 4x4 for towing. It has no problem controlling high current fans. My ONLY complaint would be that the temp sensor wiring seems very small (i.e. fragile). I encased mine in a flexible cable to protect it. The sensor position is also critical in this application. The best part is that if the sensor fails, I can toggle the controller to set the fans to 100% or just turn on the AC, which will automatically turn the fans on at 60% RPM. It's small, good quality, and ticks all the boxes with premium design features. You shouldn't be disappointed.
